TMBS Trench MOS Barrier Schottky Rectifiers

Vishay Intertechnology, Inc. expanded its offering of TMBS Trench MOS Barrier Schottky rectifiers with 12 new 45 V devices in three power package options that feature a wide range of current ratings from 10 A to 40 A. With extremely low forward voltage drops down to 0.51 V typical at 20 A, the rectifiers are optimized for use in solar cell junction boxes as bypass diodes for protection.

The devices released today include the single-chip V(B,F)T1045BP, V(B,F)T2045BP, V(B,F)T3045BP, and V(B,F)T4045BP. Each device is offered in the power TO-220AC, ITO-220AC, and TO-263AB packages.

All rectifiers feature a 200 °C maximum junction temperature in DC forward current without reverse bias (t less than or equal to 1 hour). The devices are compliant to RoHS Directive 2002/95/EC and WEEE 2002/96/EC.

The TO-263AB package offers a moisture sensitivity level (MSL) of 1, per J-STD-020, LF maximum peak of 245 °C. The TO-220AC and ITO-220AC packages feature solder bath temperatures of 275 °C maximum, 10 s, per JESD 22-B106, and are halogen-free according to the IEC 61249-2-21 definition.

Samples and production quantities of the new 45 V TMBS rectifiers are available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery starts at $0.50 per piece for the 10 A device in quantities below 10,000.
